RGB LED Matrix Panel 32x64 Can't figure out how to load my own images

[edwin8a]

Hello Everyone, I am using the P4 Matrix LED panel, I folowed the tutorials on the website bellow

https://learn.sparkfun.com/tutorials/rg … 1577053676

Everything works fine which is great, I even get the sparkfun logo to pop up when i send “l” in the serial terminal which looks like it loads in what is called the “bitmap.h” so im guessing the bitmap.h file is just the 8-bit code that then shows the sparkfun logo.

Well i get to the end of the tutorial here: (image attached) and I used a LCD image converter online tried to follow this guys tutorial on youtube on how to use it, hes not using the same board he made one of his own to i follow his tutorial loosely but i’m still getting odd shaped images that resemble nothing like what i loaded.

Has anyone worked on how to load images onto this board, and how did you do it?

Right now i take the bit map the lcd converter produces and copy and paste that by replacing what is in the “bitmap.h” file

Hi edwin8a.

The files your LCD bitmap converter are producing are not in the correct format for the Serial Paint example and that’s why they don’t look correct.

What you will need to do is draw the image on the screen you want and then you can use the “p” command to print out the array that the sketch created and save that to a .h file. Later on you can recall that array to display an image.
